+Subject: [PATCH 02/33] MIPS: ralink: add pinmux driver
+
+Add code to setup the pinmux on ralonk SoC. The SoC has a single 32 bit register
+for this functionality with simple on/off bits. Building a full featured pinctrl
+driver would be overkill.

+Subject: [PATCH 15/33] NET: add of_get_mac_address_mtd()
+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+Add gpio driver for Ralink SoC. This driver makes the gpio core on
+RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

++I2C for Ralink platforms

++Required properties :
++- compatible : Must be "link,rt3052-i2c"
++- reg: physical base address of the controller and length of memory mapped
++     region.
++- #address-cells = <1>;
++- #size-cells = <0>;
++
++Optional properties:
++- Child nodes conforming to i2c bus binding
++
++Example :
++
++palmbus@10000000 {
++	i2c@900 {
++		compatible = "link,rt3052-i2c";
++		reg = <0x900 0x100>;
